' SANITARY' DEVICE.

Application filed July 25,

' This invention relates more particularly toa device designed tobeconnected in the flushing lines of toilet fixtures for chemicalizing theWater iioiving therethrough.

It is an important object vof my invention to provide a simple devicethat may be readily mounted in the Vfluid flushing lines of toiletfixtures to chemicalize the flushing Water, whereby to effectuallydestroy or neutralizel noxious odors ising from their use.

A further object is to provide a toilet sanitation device that will holda relatively large quantity of a disinfecting chemical and arrangedl todeliver the `proper amount of disinfecting solution at each flushingoperation. v

A still further object is to provide'a 'device that will not onlychemicalize the flushing Water as used but impart a pleasant odor tothe'same.

The above'and other. objects are accomplished byV means of thedevice'described herein and'illustrated infthe accompanying drawings, inWhich; I Y f Fig. 1 is an elevation. of the device connected in theflushing lines 4of toilets.

Fig. 2 is an enlarged central vertical section through the device. y

It has heretofore been the usual practice in deodorizing anddisinfecting toilet fixtures, to feed the disinfectants from containersto the toilet hoppers, urinals and the like in small minute quantities,a container .for each fixture. This method of deodorizing anddisinfecting has proved ineffective at times due to faulty apparatus,and also eX- pensive as a larger amount of chemicals are required forthe purpose than is necessary to effect the desired result.

In the device herein described a large number of toilet fixtures may besupplied from a single device in an extremely eilicient and economicalmanner as the flushing Water is chemicalized only during a flushingoperation, thus economizing in the use of disinfectants. Further, as adeodorant is employed in connection With the device there will be nonecessity of' employing a separate deodorant as is now generally thecase.

Referringnow more particularly to the drawings Which illustrate oneembodiment of the invention, 5 designates the device as 1927'.` serialNo. 208,227.

a Whole consisting ofja cylindrical lchemical holderz. closed at itslower end and proif vided With a closure member 7 for its open upperend. This closure member has an inletopening 8 and a discharge outletlopening 9, both openings being connected. to the toilet flush line pipes10 and 11.` v

`The chemical holder 6 is provided on its lower end With a nut 12 formedintegrally therewith, andv its upper endfis eXteriora-lly threaded forengaging the circular flange 13 ofthe closure member When the device isin assembled condition. Preferably the holder is formed large enough'toreceive a pound size chemical cartridge 14, as such quantity ofldisinfecting chemical will serve ak large number of fixtures forapproximately sixty days Without. the necessity of renewal.

The top Wall 15 of the closure member is provided With a fluidpassageway 16 Whose ends terminate in the inlet and outlet opens ings,and'just belowthe top wall-15 are f formed tivo minute. oppositelydisposed openings 17, 18- in alinement with the inlet- 4and outletopenings that communicate with the interior of the chemical holder. Bymeans of these openings the Water owing through fluid passagewaywillinduce a flow4 through the upper portion of the chemical container intothe fluid passing through the flush line pipes. As the openings 17 and18 are very small it Will be apparent that the induced flow through thechemical container willl carry only a suflicient quant-ity of thechemicalized solution to impregnate the volume of Water used in aflushing operation.

In tests which I have made I have found that permangate of potassium isone of the best disinfectants, and as it is inexpensive the cost ofoperation of the device will be comparatively low. It will be understoodthat other disinfectants that are soluble in an exteriorly threadedannular flange 21 formed on the underface of the closure top wall 15,the flange being 'centrally disposed with respect vto the containertherebelow. The wall 15 of the closure is provided with a centralopening Q2`iii which is mounteda wicking Q3, the lower end beingdisposed in the liquid of the well 20 while its upper end projects intothe fluid passageway of the closure member. F rom the above it will beapparent that the wick 23 will carry a small amount of liquid deodorantby capillaryattraction into the water flow in an amount sufficient tocorrect any unpleasant odor that might arise Vfrom the use of adisinfectant.

' 'The sanitary ldevice may be connected in the flushinglines thatsupply a large number of toilets, such as are found in hotels, apartmenthouses, or office buildings, vand it may be also successfully andeconomically employed in connection with single toilets withl equallysatisfactory results.

In order that the chemical cartridge lll may be replaced by a freshone'when it becomes exhausted, globe valves 25 and Y26 are mounted inthe main flush line, a valve adjacent each inlet and outlet openings tocontrol the flow of water therethrough, and in order to prevent thedisinfectant solutiony from co-mingling with the fluid in the flush linebefore it enters the device especially when the toilets are out ofoperation, a check valve'Q? is disposed inthe flush line between thefluid -inlet and globe valve 25.

From the above it will be clear lthat I have provided an extremelysimple device that may be advantageously' and economically oassavewaformed employed to disinfect toilet fixtures and cor-V passage, wherebythe water flowing through Y the passage will be chemicalized.

2. A sanitary device for toilet fixtures' comprising a container forchemicals, a

closure for the Vupper end of said container having a fluid passageadapted for connection in a fluid supply line, said closure hav w ingyinlet and outlet openings communicat- 1 ing with the fluid passage, anda container for holding a deodorant connected to said closure, saidcontainer having an' opening communicating with the fluid passage. Y

3. A sanitary device for toilet fixtures comprising a chemical holder, aclosure cap for said holder having a transversely disposed fluidpassageway of uniform diameter formed thereabove, said passagewayadapted to be connected to a fluid pressure line, said closure havingrelatively small fluid inlet and outlet openings leading to and vfromsaid holder,said openings being disposed substantially in line with thefluid above said whereby a fluid flow will be .induced through thechemical holderto impregnate the Vfluid passing through' the fluidpressure line. l

In testimony whereof I affix my signature.
